+
+## Filing issues
+
+Filing issues on GitHub is one of the easiest ways to contribute. We value your contributions!
+
+Before you file an issue, please search existing issues to verify the issue hasn't already been filed or resolved.
+
+### Bug reports
+
+When submitting a bug report, please include the following:
+
+- Full details of your operating system (or distribution), for example, `64bit Ubuntu 18.04`
+- InfluxData Helm chart product and version you're using
+- Clear steps to reproduce the issue described, if possible
+
+The easier it is for us to reproduce the bug, the faster we can fix it.
+If you have never written a bug report before, or if you want to brush up on your bug reporting skills, we recommend reading [Simon Tatham's essay "How to Report Bugs Effectively."](http://www.chiark.greenend.org.uk/~sgtatham/bugs.html)
+
+Sharing your test cases is also helpful. If writing the data is too difficult, please zip up your data directory and include a link to it in your bug report.
+
+Please note that issues are *not the place to file general support requests* such as "how do I use something?"
+Questions of this nature should be sent to the [InfluxData Community](https://community.influxdata.com/), not filed as issues.
+
+## Feature requests
+
+We really like to receive feature requests as it helps us prioritize our work.
+Please clarify your requirements and goals to help us to understand what you would like to see added with examples and the reasons why it is important to you.
+If you find your feature request already exists as a Github issue, please indicate your support for that feature by using the "thumbs up" reaction.
+
+## Submitting a pull request
+
+1. Fork the InfluxDB repository, and then make your change on a feature branch of your fork.
+2. Generate a pull request (PR) from your branch against *master* of the InfluxDB repository.
+3. In your PR, include  details of your change (why *and* how) and any tests you performed.
+
+   > **Note:** There may be some back and forth as we finalize the change, but after that, we'll merge changes as soon as possible.
+
+To assist in review for the PR, please add the following to your pull request comment:

-##  An Open-Source Time Series Visualization Tool
+[Chronograf](https://github.com/influxdata/chronograf) is an open-source web application used to visualize your monitoring data and easily create alerting and automation rules.
 
-[Chronograf](https://github.com/influxdata/chronograf) is an open-source web application built by the folks over at [InfluxData](https://influxdata.com) and written in Go and React.js that provides the tools to visualize your monitoring data and easily create alerting and automation rules.
+The Chronograf Helm chart uses the [Helm](https://helm.sh) package manager to bootstrap a Chronograf deployment and service on a [Kubernetes](http://kubernetes.io) cluster.
 
-## QuickStart
-
-```bash
-helm repo add influxdata https://helm.influxdata.com/
-helm upgrade --install chronograf influxdata/chronograf --namespace monitoring
-```
+## Prerequisites
 
-## Introduction
+- Helm v2 or later
+- Kubernetes 1.4+
+- (Optional) PersistentVolume (PV) provisioner support in the underlying infrastructure
 
-This chart bootstraps a Chronograf deployment and service on a Kubernetes cluster using the Helm Package manager.
+## Install the chart
 
-## Prerequisites
+1. Add the InfluxData Helm repository:
 
-- Kubernetes 1.4+
-- PV provisioner support in the underlying infrastructure (optional)
+   ```bash
+   helm repo add influxdata https://helm.influxdata.com/
+   ```
 
-## Installing the Chart
+2. Run the following command, providing a name for your Chronograf release:
 
-To install the chart with the release name `my-release`:
+   ```bash
+   helm upgrade --install my-release influxdata/chronograf
+   ```
     
-```bash
-helm upgrade --install my-release influxdata/chronograf
-```
+   > **Tip**: `--install` can be shortened to `-i`.
 
-The command deploys Chronograf on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
+   This command deploys Chronograf on the Kubernetes cluster using the default configuration. To find parameters you can configure during installation, see [Configure the chart](#configure-the-chart).
 
-> **Tip**: List all releases using `helm list`
+  > **Tip**: To view all Helm chart releases, run `helm list`.
 
-## Uninstalling the Chart
+## Uninstall the chart
 
-To uninstall/delete the `my-release` deployment:
+To uninstall the `my-release` deployment, use the following command:
 
 ```bash
 helm uninstall my-release
 ```
 
-The command removes all the Kubernetes components associated with the chart and deletes the release.

 ## Persistence
 
 The [InfluxDB](https://hub.docker.com/_/influxdb/) image stores data in the `/var/lib/influxdb` directory in the container.
 
-If persistence is enabled, a [Persistent Volume](http://kubernetes.io/docs/user-guide/persistent-volumes/) associated with Statefulset will be provisioned. The volume is created using dynamic volume provisioning. In case of a disruption e.g. a node drain, kubernetes ensures that the same volume will be reatached to the Pod, preventing any data loss. Althought, when persistence is not enabled, InfluxDB data will be stored in an empty directory thus, in a Pod restart, data will be lost.
